Dry shaving apparatus with an auxiliary frame which is displaceably insertable in the direction of the lower cutter, is held via resilient catching means in the end cheeks of a shaver casing or a cutting head frame, is unlocked by means of unlocking keys which act on ascending ramps provided on the catching means, and is moved through a predetermined distance in the removal direction.

The invention relates to a process for the production of composites for dental practice, based on finely divided silicic acid and polymerizable monomers. The composite material according to the invention can be handled readily even at a filler content of > 50 % and is easy to process. It allows the production of high-gloss smooth surfaces. The object is achieved according to the invention in that ...

PURPOSE:To pierce many minute through-holes of good form in a short time and to improve its efficiency by removing copper layers on both sides of a part where holes are to be pierced by etching and then piercing by irradiating laser light. CONSTITUTION:Desired hole diameter 3a, 4b in copper foils 2a, 2b at positions to be pierced is removed by etching. An oxide film of copper is removed by immersi...

PURPOSE:To simplify the manufacturing process of an FRP leaf spring device and to enhance the strength and flexure thereof, by securing an FRP leaf spring formed in its one end section with an eye member, at its the other end, unmovably to a vehicle body while the eye member is movably supported to the vehicle body by means of a shackle or the like. CONSTITUTION:A leaf spring device 11 is composed...

A sling structure is defined by a flexible quadrilateral sheet panel which is defined by longitudinal side rails (22,24) of substantially inelastic material connected by a crossband structure (36,38) of elastic material extending between the side rails. One end of the flexible sheet panel is mounted on a vertical wall (16,18) of a vehicle body compartment (12), preferably by a reel (32) for windin...

PURPOSE:To realize marking of ink jet system or printer system, etc. and improve marking efficiency, or manufacturing efficiency of semiconductor device by forming a marking portion with a substance which assures high water absorbing property. CONSTITUTION:A heat radiating fin 12 consisting of aluminum is attached to the surface opposed to the pellet 3 attaching surface of substrate 2 with a bondi...

PURPOSE:To form a light weight substrate, reduce a thermal resistance and prevent crack or missing of material by collision with other substance by forming a substrate which loads a material for semiconductor device, particular ly a semiconductor element with Al metal. CONSTITUTION:Since a substrate 1 which loads a semiconductor chip is formed with Al metal, an insulating film 7 consisting of an o...

A method and apparatus for presenting real-time information for viewing is disclosed wherein a projection lens projects an image of a liquid crystal display onto the surface of a holographic optical element diffuser. The liquid crystal display is driven so as to contain real-time information and is illuminated by substantially monochromatic light. The diffuser diffracts the real-time information t...

According to the method of this invention for fixation of incinerator ash, incinerator ash containing SiO2 and Al2O3 is incorporated with NaOH or NaOH and an SiO2-containing substance in such an amount that the resulting mixture contains 25 to 90 wt % of SiO2, 2 to 10 wt % of Na2O, and more than 3 wt % of Al2O3 which is less than the content of SiO2 in terms of mol %; 100 parts by weight of the mi...

The invention relates to a device for monitoring the ink supply in ink jet printing units, the prime object of which device is to realise a fluid level display which, without adverse effects on the ink, is as independent as possible of the ink parameters and of fluctuations in the ink level which vary as a function of time and temperature. The object of the invention is therefore to develop a moni...

A substance to be treated is brought into a treatment column (10) and kept in suspension (11) in the latter by the injection (A) of a fluidizing gas into the bottom part of the column. According to the invention, a plasma is injected (D) into the column in at least one direction within a radial plane relative to the column. Preferably, the plasma is produced by high-frequency induction and injecte...

In a drum-type washing machine (1), the washing-cycle speed of the laundry drum (3) is newly determined by a microcomputer (5) in each started washing program as a function of measured values relating to the load quantity, the type of laundry and the particular predetermined program water level and is used as a basis for the further program flow.
